Every movement must be just right when the blade and rotor hub of a wind turbine are married together at a dizzy height.  Because screwing the rotor blade onto the rotor hub 100 metres above the ground represents a major bonding technology challenge. Heavy-duty threaded bushes are bonded into the fibre-reinforced flange on the blade holder of each blade – and the bond must be absolutely rock solid.

Despite the increase in production capacities, the demand for carbon fibres continues to be far greater than the supply. This is evident from the annual market survey by the AVK – Industrievereinigung Verstärkte Kunststoffe e.V. The worldwide capacity in 2007 is estimated to have been 55,000 tons. The applications are multifarious and consist primarily of the sports sector, wind energy, the oil industry, the automobile and transport sector as well as civil engineering. By 2010, an annual increase in the demand for CRP is predicted to be between 14 and 16 per cent. This is due to the development of new applications over and above the previous use. Current new developments can be found, e.g. with hydrogen tanks, although the main application continues to be aviation. Experts think that even though fibre production will experience a double-digit increase as expected, there will continue to be bottlenecks at least in the medium-term. Read Full Post
